Question about using JavaMail API to read the calendar folder...

Hi,
I've made an application that goes to the mail server, fetches all mails in the calendar folder and tells you the meetings you have in a particular day.
I'm using JavaMail API for this. My problem is that the application is very slow because I'm forced to fetch (one by one!) the contents of every message.
My question is: How can Outlook show so fast the mettings you have? Do they have a specific API that allows them to get the right info by only calling certain methods? Is there something similar in Java?
Thaks for your help!
Note: I use method:
folder.fetch(allMessages, fetchProfile);howerver the fetchProfile class does not allow me to specfy that I want to dowload the contents of the message (you only can specify the content_info); specifying all headears does not help me either.

Clarification:
The VI you have posted will work as following:
1) The task will read 2 analog inputs (ai0, ai3).
2) The acquisition starts, oncece digital signal (trigger) is detected on PFI0
3) The sampling rate will be as specified in "rate" control - it is continuous analog input acquisition, which means that after trigger is received (point 2), the board will start to generate hardware clock with frequency you specify as "rate"
4) with each rising edge of that hardware clock, the measurement is taken, and stored into buffer of driver.
5) DAQmx read will try to read "number of samples per channel" number of samples each time is called - and if there is not enough measurement stored in buffer (step 4), then DAQmx read will wait until DAQ card will measure reaquested number of samples (or timeout occurs before requested number of samples has been acquired)
6) DAQmx read will be then called 1000 times - so totaly you will read 1000 * "number of samples per channel" number of samples.
You do not have to be worried about speed of the loop. In fact, if you need to read just 1000 samples, with 1kS/s, then you can remove for loop and you can change measurement mode from continuous to finite samples, and specify number of samples to read to be 1000. You will read them all properly. I recomend you to read User Manual for your DAQ device - lets say M Series User Manual.
I hope it is clear now.

Order, Paginate and List emails in JavaMail API

Am able to sendm and retrieve emails in java using JavaMail API but am having a problem. I would like to sort emails by date, subject, sender etc and also display only a subset of emails using pagination.
            Message[] msgs = folder.getMessages();
            FetchProfile fp = new FetchProfile();
            fp.add(FetchProfile.Item.ENVELOPE);
            folder.fetch(msgs, fp);The function folder.getMessages(); can take 2 arguments (from_index,to_index), but this is according to the way mail server will transalate. POP server will arrange by date while IMAP is unordered. I would like to order the mails then fetch the getMessages(from_index,to_index).
Another posible way am seeing is fetching all mesages using getMessages() put them in a temporary storage(eg. vector or list), order them and then fetch only the page i want. But this could be very costly in terms of processing resources, which makes me believe there is a better approach and it seems i cant find it.
Can somenone please advice me on what to do. I will be very greatful.
Edited by: kagara on Aug 27, 2008 12:27 PM

With POP3 you have no choice but to download the messages and sort them in the client.
The POP3 protocol simply doesn't provide a "sort" option.
With IMAP, some IMAP servers support a "SORT" extension, although JavaMail doesn't
support it yet.

Problem Sending mails in a loop using JavaMail API

Hello All,
I am sending emails in a loop(one after the other) using JavaMail API,but the problem is, if the first two,three email addresses in the loop are Valid it sends the Email Properly, but if the Fourth or so is Invalid Address it throws an Exception....
"javax.mail.SendFailedException: Sending failed;"
nested exception is:
javax.mail.SendFailedException: Invalid Addresses;
nested exception is:
javax.mail.SendFailedException: 450 <[email protected]>:Recipient address rejected: Domain not found......
So if i want to send hundereds of emails and if one of the Emails inbetween is Invalid the process Stops at that point and i could not send the other emails in the Loop......
How Could i Trap the exception thrown and handle it in such a way, so that the loops continues ..
Is there something with the SMTP Server....?
The code which i am using is as follows....
<Code>...
try {
InitialContext ic = new InitialContext();
Session session = (Session) ic.lookup(JNDINames.MAIL_SESSION);
if (Debug.debuggingOn)
session.setDebug(true);
// construct the message
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(eMess.getEmailSender()));
String to = "";
msg.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to, false));
msg.setRecipients(Message.RecipientType.BCC,
InternetAddress.parse(eMess.getEmailReceiver(), false));
msg.setSubject(eMess.getSubject());
msg.setContent(eMess.getHtmlContents(),"text/plain");
msg.saveChanges();
Transport.send(msg);
} catch (Exception e) {
Debug.print("createAndSendMail exception : " + e);
throw new MailerAppException("Failure while sending mail");
</Code>....
Please give me any suggestions regarding it....and guide me accordingly..
Thanks a million in advance...
Regards
Sam

How about something like the code attached here. Be aware it is lifted and edited out of an app we have here so it may require changing to get it to work. If it don't work - don't come asking for help as this is only a rough example of one way of doing it. RTFM - that's how we worked it out!
SH
try {
Transport.send(msg);
// If we get to here then the mail went OK so update all the records in the email as sent
System.out.println("Email sent OK");
catch (MessagingException mex) {
System.out.println("Message error");
Exception ex = mex;
do {
if (ex instanceof SendFailedException) {
if (ex.getMessage().startsWith("Sending failed")) {
// Ignore this message as we want to know the real reason for failure
// If we get an Invalid Address error or a Message partially delivered message process the message
if (ex.getMessage().startsWith("Message partially delivered")
|| ex.getMessage().startsWith("Invalid Addresses")) {
// This message is of interest as we need to process the actual individual addresses
System.out.println(ex.getMessage().substring(0, ex.getMessage().indexOf(";")));
// Now get the addresses from the SendFailedException
SendFailedException sfex = (SendFailedException) ex;
Address[] invalid = sfex.getInvalidAddresses();
if (invalid != null) {
System.out.println("Invalid Addresse(s) found -");
if (invalid.length > 0) {
for (int x = 0; x < invalid.length; x++) {
System.out.println(invalid[x].toString().trim());
Address[] validUnsent = sfex.getValidUnsentAddresses();
if (validUnsent != null) {
System.out.println("Valid Unsent Addresses found -");
if (validUnsent.length > 0) {
for (int x = 0; x < validUnsent.length; x++) {
System.out.println(validUnsent[x].toString().trim());
Address[] validSent = sfex.getValidSentAddresses();
if (validSent != null) {
System.out.println("Valid Sent Addresses found -");
if (validSent.length > 0) {
for (int x = 0; x < validSent.length; x++) {
System.out.println(validSent[x].toString().trim());
if (ex instanceof MessagingException)
ex = ((MessagingException) ex).getNextException();
else {
// This is a general catch all and we should assume that no messages went and should stop
System.out.println(ex.toString());
throw ex;
} while (ex != null);

MacBook Air: the right choice for a College student?

Hello there!
I'm buying my first Apple laptop in the near future (probably tomorrow as I like to buy things in store and not online and I live roughly 75 miles from the nearest Apple store and am heading to the mall it's located in on a shopping trip tomorrow, anyway). I currently have a 3 year old Dell that has no battery life at all (it has to be connected 24/7 to an outlet, the mouse clicky button doesn't work, it overheats, and the hardrive has already been replaced not once but twice) and I don't use it for anything other than school, facebook, watching movies via netflix, skype, and listening to music. I've been doing months of research and all has lead me to Apple.
I want this laptop to last me until I am done with my masters and into the first couple years of my teaching career, so roughly 6 years. Is that too much to ask from this machiene?
I'm inlove with the thiness, lightness and portability of the Macbook Air. I use my laptop a lot, this semester I'm finishing out my core requirements and a lot of them are "bullsh*t" classes where I can do nothing and get an A. I would therefore have my laptop with me, I also bring it to friends rooms to study and relax. My goal is to have a laptop that I can write papers, continue to watch movies and use it as a basic machiene. I barely use a cd drive (my aunt is willing to by the drive that goes with the Air) but when I do it's just for burning music to my itunes. I want a machiene that will have a long lasting battery life - that's my biggest concern.
My roomate has a Macbook Pro and keeps telling me that I'd hate the Air.
I've read that people do not like it as it does not have a backlit keyboard. That doesn't bother me as my keyboard currently isn't backlit.
I've also read that people continue to prefer the pro over the air but I am not a fan of the pro just as it is so much bigger.
I barely ever use my USB drive, when I do its to transfer over files that need to be printed. So having only two of them means nothing to me really.
I'm just looking for assistance to help me make my decision. I feel like I already made it but I just want to be sure that I'm making the right choice.
My personal pros/cons:
Pros: lightweight, small, highly portable, amazing webcam, excellent battery life
Cons: it's so thin I feel like I would snap it in two pieces
Thank you so much!

Listen to us, Lovekate!
We know you're eager, but hold out just a little longer--maybe a week or two--for the update! Please! It's the smart thing to do because it may give you options you can use. Kate! Look away from the machines. This way! This way! You can do this. If you don't, you'll feel buyers remorse and that's not good. Hold off. You'll be happy you did...also, don't forget, when you do buy, you get a student discount.
From what you say, you've found the computer you love and don't need any encouragement from us. But here's advise for what you can say to your friends:
(1) To those telling you to get the Pro--you are not going to buy more than you need. With Clouds, and online mail and external hard drives, there is no need for you to haul around anything made heavy with a huge hard drive you'll never fill up. And the Air can do anything a Pro can do excepting update to a bigger hard drive (which you've just explained you don't need--like you don't need the CD drive). And the 13" actually has a longer lasting battery than the 13" Pro.
(2) Why should you get a computer you don't love, and therefore is no fun or joy for you to work on, rather than a computer you love, which you will love working on? Apple rule, "Always get what you love."
(3) To your Dad, you are buying something very like a car. And like a car, if you buy one cheap, it will cost you if it breaks down, needs repairs, or needs replacing. Needing to buy a new cheap car every other year can add up to the same cost as buying a new car that will last you ten years. You are buying a computer that will last you, be reliable, and not need repairs thus interfering with your productivity (by the way, get Apple Care--adds two more years warranty for a total of 3 years--trust us on this. If you can't afford it now, you can hold off buying it till the end of the first year, but do get it!). Apple computers also have good resale value.
In short, as much as it costs, it will be worth it.
Hope that helps, and remember...hold out! or if you've already bought it--you have 14 days to return it.

Getting exceptions while sending mail using javamail api

Hi to all
I am developing an application of sending a mail using JavaMail api. My program is below:

It compiles fine but showing exceptions at run time.Please help me to remove these exceptions.I am new to this JavaMail and it is my first program of javamail.Please also tell me how to use smtp server.I am using MTNL 's internet connection having smtp.bol.net.in server.
exceptions are:
Here is exception

Did you find the JavaMail FAQ?
You should talk to your ISP to get the details for connecting to your server.
In this case I suspect your server wants you to make the connection on the
secure port. The FAQ has examples of how to do this for GMail and Yahoo
mail, which work similarly. By changing the host name, these same examples
will likely work for you.

Problem accessing gmail with IMAP using JavaMail APIs

Hi,
I am trying to access my gmail account with JavaMail API. I am able to access it using pop3s but not with IMAP.
I have used following details:
protocol: imap
host: imap.gmail.com
port: -1 (also tried with 993) but no success.
My basic code is
url = new URLName(protocol, getHostname(), 993, mbox,
                          getUsername(), getPassword());
         Properties props = null;
         try {
          props = System.getProperties();
         } catch (SecurityException sex) {
          props = new Properties();
         session = Session.getInstance(props, null);
          session.setDebug(true);
        store = session.getStore(url);
        store.connect();
        folder = store.getFolder(url);
        folder.open(Folder.READ_WRITE);Any pointers?
Thanks.

Changed protocol from "imap" to "imaps"....and used port 993...and its working!!!!

Timed sequences. Is that hte right choice and how does it works!

Hi!
I'm a newbie in LV, and I'm trying to create a VI that is capable of controlling a small filtration unit I have build as a part of my engineering studies.
I have to control three magnetive valves which are connected to the digital output port Do0, Do1 and Do2 on my MyDAQ 6009 USB device.
I have to control the sequence by which the valves opens / closes as to avoid damage of som sensitive pressure transmitters. How do I manage to programme a time controlled sequence that opens and closes the valves in the right order and , in reverse order, repeats the sequene after a user defined choice of time?
I have looked at the "Timed sequence" but cant find a "down to earth" description on how to use it.
Maybe my problem is a bit to general. In that case I can surely help with a clarification if needed.
I hope someone can help me with my problem. By now I have spent 6 hours in watching different tutorials without any luck.
Thanks in advance
Henrik
Solved!
Go to Solution.

Hi Anders!
I have looked on the State Machine solution, but couldn't really figure out where to start. As I mentioned, I'm a newbie. All I have done so far is data logging and working with analog signals (temperature logging, controlling a pump and so on). I have build a filtration unit as a part of my studies to become a chemical engineer. In order to clean the ceramic membrane in use, there is a procedure where the fluidstream is pumped back in to membrane to loosen fouled particles etc (called backflush). This is done with high pressure air. I have mounted three magnetic valves to be able to control this process.
Valve one and two has to close approx 0.5 sec before valve three opens. Valve three is allowing the high pressure air to push fluid in reveres direction and valve one is protecting a pressure transmitter with a max. overload pressure [bar] below the required pressure. After a userdefined number of seconds, the process has to be repeated in reverse order. The three valves are connected to digital I/O channel 0,1 and 2 on the USB 6009. With the Measurement and Automation explorer testpanel I can open and close the valves manually, so the connection is established. I don't have access to a PLC, which probably would be the right choice for my problem.
If you could help I would appreciate it a lot. My thesis isn't about building a filtration unit. It is more the process using it, and that is not possible right now
If the above information is insufficient, I will provide any information needed.
Best regards
Henrik

Any changes in JavaMail Api

X.400 instead of SMTP Protocol and Javamail API

We have developed a workflow application on Domino 5.0.7. The SmartHost is "MS Exchange Server", because the application will only be accessed by browsers, we are using javaagent to send the email notifications. Due to some domain restrictions on MS Exhchange servers we have implemented Javamail API on the domino server, and it worked fine (I mean the messages were received by the Exchange Clients, using the SMTP addresses like [email protected]). As we dont have available SMTP addresses for all end users in the company we need to use the X.400 addresses. Is there anyone, can help guide about either the avaiability of any X.400 javamail api, or how to use mapi etc? I know it is little bit challenging, but we are struck. thanks

Currently, the latest version of the JavaMail 1.2 API, X.400 transport protocol is not supported yet. Only the transport SMTP - a message Transport protocol, for sending messages to a server, is supported.

Third Party APIs in Java Language which doesnot use JavaMail APIs

Hi Pals,
Is there any third party java mail APIs available which doesnot using Sun JavaMail APIs? The third party would have its own APIs which does not use javax.mail. I have to code in Java Platform so if the APIs are java based its nice and useful to me.....
Thanks & Regards,
Prakash

Hi,
I am using Javamail APIs to send mails. Sometimes Mcafee blocks the mails and its not allowing javax.mail package. Thats why i would like to go for some other third pary which uses their own APIs......What makes you think a third party API would be less prone to interference by McAfee?

Hello Everyone, I want to purchase an ipad ,please suggest whether ipad mini is the right choice to go for or not?

I am planning to buy an ipad mini, please suggest me whether its the right choice to go for or not ?
Hows the display?

The Ipad 4 has a stronger processor, and better graphics and display than the Mini. but they can basically do the same things.
Obviously one is smaller than the other, but at the end, the games will still play on both, and you may not even notice a difference.

OWB: is that my right choice?

Hi,
my knowledge about OWB is still very limited, so I'd like to ask you if this product could be a right choice for the following situation:
- I have an existing Oracle datawarehouse, being fed by a number of source databases (in an old-fashion manner);
- I'm going to interface new sources to this dwh, and I mean to replace any ETL used up to here with OWB.
My primary concern: is there a point in using OWB to feed an existing DWH? I've no need for new design, actually. May I use only the ETL tools in OWB, technically speaking? would it be a pointless choice to use OWB only to let sources DBs and target DWH communicate?
Thanks in advance for any suggestment.
Regards,
Emanuele

Arron,
The next major release does not have a version number assigned yet. That release is expected at the end of the year.
I respect your opinion on comparing OWB to other ETL products. However if you can list specific areas for improvement of OWB, it will be helpful. Generic statements like "it's not the best" and "weak" do not provide an actionable feedback to OWB development.
Also your opinion must be viewed in conjunction with what others in the market think. OWB has been repeatedly praised by leading analysts, industry press and other users. For example see this thread Re: comparative case study between ETL tools with messages by Roald Heie and Michael Brian Armstrong-Smith.

RMI: Is it the right choice?

I want to make an application that connects to 1 other peer. So I'd run the application and if I type in the IP of someone else running the same application, we can connect to each other and do stuff like chatting. Is RMI the right choice to make this happen?

I would use Apache MINA library. Its easy to use, fast, more firewall friendly than RMI, more language-independent transmission format. http://mina.apache.org/
Really. Where does it say that MINA knows a firewall from third base?
Mina is a Java NIO library that just does TCP and UDP communications and intra-process pipes.
It's not a competitor for RMI in any sense that I'm aware of.

Is JavaMail API right choice
